[quote name='rct316']idk cuz i got 6 codes from gamestop, and 4 of the codes worked for my friends (all in US), but 2 of them said invalid. so idk wut to think of it lol[/QUOTE]
you might have to move the characters around, some people in the thread said that is how they got it work.
Unless people have problems with a yahoo account, I most likely signed after all the codes have been giving out, since no code in my email.
